Causes

Dark circles under the eyes are usually caused by being tired. Sometimes, what appear to be dark circles under your eyes may merely be shadows cast by puffy eyelids or hollows under your eyes that develop as a normal part of aging.

Some of the most common causes of true under-eye circles are:

• Allergies
• Atopic dermatitis (eczema)
• Contact dermatitis
• Fatigue
• Hay fever (allergic rhinitis)
• Heredity
• Skin color irregularities
• Rubbing or scratching your eyes
• Sun exposure, which prompts your body to produce more melanin, the pigment that gives skin its color
• Skin changes that happen with aging
